RISShort-Range Forecasts with the GISS Model of the Global Atmosphere
Publisher: American Meteorological Society
Abstract: A nine-layer, primitive equation (PE) model of the global atmosphere developed at the Goddard Institute for Space Studies (GISS) has been used to generate six 48-hr forecasts during December 1972 and January 1973. Operational ...
Objective Sea-Level Pressure Analysis for Data-Sparse Areas
Publisher: American Meteorological Society
Abstract: A computer procedure, described in an earlier study, uses the wind speed field near the ocean surface in combination with a small number of observations of pressure and wind velocity to specify the maritime sea-level ...
Objective Analysis of Sea-Level Winds and Pressures Derived from Simulated Observations of a Satellite Radar-Radiometer and Actual Conventional Data
Publisher: American Meteorological Society
Abstract: A computer-based procedure is developed that combines a field of simulated satellite-derived wind speeds with a limited amount of conventional surface data so as to recover the surface pressure field and the vector wind ...
A Comparison of Low-Level Trajectories in an Urban Atmosphere
Publisher: American Meteorological Society
Abstract: Throughout the month of June 1965 tetroons ballasted for 150?300 m altitude were released and radar-tracked in New York City and environs. The study evaluates the skill with which data from both a dense mesoscale network ...
Tropical Impacts of SST Forcing. A Case Study for 1987 versus 1988
Publisher: American Meteorological Society
Abstract: The response of the NASA/Goddard Institute for Space Studies GCM to large tropical sea surface temperature (SST) anomalies is investigated by evaluating model simulations of the particularly contrasting summer monsoon ...
The Influence of Ocean Surface Temperature Gradient and Continentality on the Walker Circulation. Part I: Prescribed Tropical Changes
Publisher: American Meteorological Society
Abstract: A coarse-mesh, global climate model developed at the Goddard Institute for Space Studies (GISS) has been used to assess the influence of ocean surface temperature (OST) gradient and continentality on the Walker circulation. ...
The Sensitivity of WRF Daily Summertime Simulations over West Africa to Alternative Parameterizations. Part II: Precipitation
Publisher: American Meteorological Society
Abstract: his paper evaluates the performance of the Weather Research and Forecasting (WRF) Model as a regional atmospheric model over West Africa. It tests WRF?s sensitivity to 64 configurations of alternative parameterizations in ...
Dynamic Downscaling of Seasonal Climate Predictions over Brazil
Publisher: American Meteorological Society
Abstract: Climate projections for March?April?May (MAM) 1985 and 1997 made with the NASA Goddard Institute for Space Studies (GISS) GCM over South America on a 4° latitude by 5° longitude grid are ?downscaled? to 0.5° grid spacing. ...
